uucleus ; the remains of ii I'ood-vacuole are seen ])elow. In fig. 7 the 

 process is more advanced ; vacuoles surround two of the ingested 

 particles, which are being digested. 



Fig. 8. — Phagocyte after digestion. Vacuoles empty. The nucleus 

 has become loljulate. 



Fig. 9. — Phagocyte in the resting condition, showing numerous small 

 pseudopodia. Nucleus fragmented. 



Fig. 10. — Small roimd-cells. The characteristic feature of these cells 

 is the small amount of cytoplasm, which forms a thin layer round the 

 nucleus. 



Figs. 11-18. — Hydrophilns. Phagocytic cells are represented in 

 figs. 11-17 ; small i-ound-cells in fig. 18. 



Fig. 11. — Phagocytic cell, with pseudopodia. seen on edge. A small 

 particle surrounded by a vacuole lies in one pole. 



Figs. 12-ll.s — Phagocytic cells with ingested particles. After a tiuie 

 these particles l:)ecome enclosed in vacuoles, and. as digestion proceeds, 

 lose their staining reaction. 



Fig. 15. — Phagocytic cell. Polar view of mitotic division-figure. 



Fig. 16. — Phagocytic cell. Ecpiatorial view of mitotic division-figures. 



Fig. 17. —Large phagocyte with abundant cytoplasm containing 

 numerous flaky granules. 



Fig. IS. — -Small round-cells. The characteristic feature of these cells 

 is the scanty cytoplasm surrounding the nucleus.
